CVE-2026-64298

A flaw was found in the Linux kernel's NFSv4 implementation. A local user could exploit a vulnerability where opening a file with OTRUNC truncate and ORDONLY read-only flags would bypass the necessary write permission checks. This oversight allows an attacker to truncate a file without having...

CVE-2026-64280

A flaw was found in the Linux kernel's dfl-afu FPGA driver. A local user could exploit this vulnerability by providing an excessively large length value during Direct Memory Access DMA mapping operations. The system incorrectly truncates this value, leading to memory corruption. This could allow ...

CVE-2026-64292

A flaw was found in the Linux kernel's iommufd component. A local user can exploit this vulnerability by allocating large veventq queues, which are processed inside a spinlock. This can lead to the exhaustion of atomic memory reserves, resulting in a Denial of Service DoS condition...

CVE-2026-64543

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC module. A use-after-free vulnerability exists in the tipcdiscrcv function, where the discoverer object can be prematurely freed while still being referenced. An unprivileged local user can exploit this flaw by...

CVE-2026-64551

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP. This vulnerability allows a remote attacker or a local unprivileged user to potentially access and disclose sensitive information. By sending a malformed error message, the system can be tricked into reading and the...

SUSE CVE-2026-17523

A flaw was found in the Linux kernel in net/can/bcm.c in can: bcm, where an unprivileged local user can exploit this vulnerability to execute arbitrary code within the kernel, which leads to a local privilege escalation LPE. This allows the attacker to gain root privileges and take full control o...

CVE-2026-43681

CVE-2026-43681 is a local, kernel-memory-access buffer overflow in macOS components fixed by improved bounds checking. Affects macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, and macOS Tahoe 26.6. The vulnerability enables a local user to read kernel memory. The CVE entry confirms the root cause as a ...
